HTC Thunderbolt owners are about to get a taste of the latest, sweetest Gingerbread, according the above leaked document and the word of one of our Verizon ninjas. The Android 2.3.4 update is about to roll out for Verizon’s 4G LTE handset, and plenty of video calling features are packed inside. Not only will the update feature GTalk video calling, but Skype Video will also make the journey to the Thunderbolt. That’s the same Skype Video that was supposed to launch bundled with the handset. The Skype Video we saw leaked but have still not seen officialy released months after the Thunderbolt’s debut. And when might we expect this treat? If the word of our tipster holds true, June 30th is the target release date. Take that much as a rumor for the time being.
